Even more mysteriously, tectal circuitry shows oscillations of activity in response to a periodic visual stimulus, which can continue long (tens of seconds) after the stimulus has stopped.
Large oscillations of cellulase activity in the compost have been observed which co-ordinate with mushroom fruiting body production and oscillations of activities of fruiting body metabolic enzymes [ 16, 17, 65].
This sequential action of two opposing enzyme produces an oscillation of RpaA activity that is offset from that of the KaiABC core clock.
Throughout the experiment, oscillation of promoter activity could be clearly observed.
For example, oscillation of p35 activity is associated with cell-cycle arrest and recovery, whereas a single long-lasting activation of p35 leads to apoptosis.
Further studies should address whether sugar, direct light, or signals related to internal rhythms influence the diurnal oscillation of GS activity.
Resting state, a condition in the absence of stimulus or cognitive task, is important to understand the spontaneous oscillation of brain activity and is considered as a baseline condition in many neuroimaging studies [ 21- 24].
The oscillation of CDK activities regulates cell cycle progression in response to a wide array of cell signaling pathways.
Plotting the location of peak Rac activity on the longitudinal axis against time revealed unexpected oscillations of Rac activity between the front and back of chemotaxing neutrophils, and albeit these oscillations being noisy, they tended toward periodicity.
The individual topics range from the "microscopic level", where new exciting results on specific oscillations of neural activity are reported, to computer simulations of perception, and finally psychological experiments at the "macroscopic level".
